水處理中什么是三層混合床?

我們知道:普(pu)通混(hun)合床是陰、陽(yang)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)相(xiang)混(hun)，設有(you)中間(jian)排(pai)管(guan)，再(zai)生(sheng)時，堿液(ye)從上而下從中間(jian)排(pai)管(guan)排(pai)出，酸從下而上也從中間(jian)排(pai)管(guan)排(pai)出。由于陰、陽(yang)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)分層(ceng)(ceng)(ceng)不清，而中間(jian)排(pai)管(guan)本身也要占(zhan)一(yi)定的(de)(de)容(rong)積，因此，再(zai)生(sheng)時堿液(ye)會接(jie)觸到陽(yang)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)，酸液(ye)會接(jie)觸到陰樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)，形(xing)成部(bu)分陽(yang)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)變(bian)成鈉(na)型(xing)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)，部(bu)分陰樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)變(bian)成氯型(xing)，而嚴重影響出水水質。為了避免混(hun)合床的(de)(de)上述缺(que)點，在(zai)強酸性、強堿性的(de)(de)陽(yang)、陰樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)中間(jian)，加(jia)一(yi)層(ceng)(ceng)(ceng)惰性樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)。這層(ceng)(ceng)(ceng)惰性樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)相(xiang)對密度是在(zai)陰、陽(yang)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)之間(jian)，這樣，在(zai)反洗分層(ceng)(ceng)(ceng)轉入(ru)再(zai)生(sheng)時，就可將樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)從上而下分為三(san)層(ceng)(ceng)(ceng):陰樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)-惰性樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)-陽(yang)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)，這就稱為三(san)層(ceng)(ceng)(ceng)混(hun)床。

其中，惰性樹脂是一種偏丙烯 酸鹽及二乙烯苯(ben)的聚合物(wu)，呈圓球形，密(mi)度為704~736g/L、顆粒(li)大小(xiao)25~40目、有效(xiao)直徑0.45mm，均(jun)勻系(xi)數為1.9。
